Sensor Life
During the trial there were no Sensor insertion problems and Sensors may be
worn for up to 7 days (168 hours). To estimate how long a G4-Global Receiver
Sensor will work over 7 days, the 71 Sensors were evaluated to determine how
many Days (hours) of readings each Sensor provided. Table 10, below, displays
how long you can expect a Sensor to last after insertion. For example, 89% of
the sensors lasted more than 6 and up to the full 7 days (144-168 hours).
There were 6 Sensors that did not last at least 6 days or more than 144 hours.
Five (5) of those sensors became non-functional due to an Early Sensor
Shut-off, and 1 Sensor ended before 6 days because the subject bumped the
Sensor and it fell off.
Table 10. Estimated G4-Global Receiver Sensor Life
Number of Days of Use (Hours) Percentage of Sensors
1 (24 hours) 1%
2 (48 hours) 1%
3 (72 hours) 6%
4 (96 hours) 0%
5 (120 hours) 0%
6 (144 hours) 3%
7 (168 hours) 89%
